Appliati'on filed October 4, 1919. 'Serial No., 328,577.

the iront end reni' carrying Wheels in which the case olh containing the transmission. and diierentini gearing is utilized as EL part thereof and in which the general supporting stresses are not applied to the casing'o the motor used to lLliive the gearing.

This result is attained by providing a freine extending around the motpr and ,sup-

il et its front end by the front -axle eure/l et its rear directly to the trans- 1 gear-case. As a. result of this constrnctioin the motor-casing is relieved of snpperting stresses, and ufurthermore, it is possible to remove the motorA Without disturbing the general supporting structure.l

.mother object of the invention is to provide en improved fireftfconnection by which etresses will'be yieldingly applied! wel? to the geancose forming a port of supporting structure. i

.in the drawings: Figure l is e pien of e tractor embodying the invention. Fig. 2 is t si ve elevation, the traction-Wheel at the near :'sifle being ornitted. Fig. 3 is a yvertical section through lthe geler-cas.

The tractor comprises e pair of rear trectioi'i--wiieeie 5 supporteflon and driven by eniesections d -which are mountedin vsleeves (i which ere secured to the sides of, and form extensionson, the reel.' portion Aof the geen casing-i? and e pair of front Wheels dirigihly' connected to e front axle 9. The front portion of the case 7 contains variable speed trsnsmissiongeering b and the rear portiony contains diierentinl gearing c which may be of the type exemplified in an zlpplicntion ileti loi/.me of even ditte. herewit i, serially nnmhered'328,l87. T his cese is adopted to serve os e port of the supporting structure between. the front and rea-r portions of the tractor and together with a Usheped frame i() comprising sides 1l und a. front 12, to which the front axle 9 is pivotolly connected 'to swing' vertically, constitutes the general supporting structure between the front rear Wheels. The rear end o' eecii side ii is secured, .13, to one sicie of the "liront portion 'of toe treneinissi n' eeen-cese Z "which is provitiezgl 'with ribs @all between 'which seid sides are disposed. A motor i5 is provided with ings 1G which are secure' to the sides il. The casing l? of the motor is provided with a housing i8 with e, flange 19 which is secured to o. corresponding flange Sli 20 on the `front end of the gear-case 7. The

front end of the case 7 is formeel with e housing 21 which, together with the housing 1 8 of the motormening. forms en inolosure Jfor the usuel lywvheel' and the clutch. Q53 between e crank-shaft ot the motor enel the drive-shaft 22 for the variable speed mission gearing A characteristic of the structure set forth is that the motor 17 is independently carried by the supporting structure and may he flis- -connectecl from the onse 7 ond removed without disconnecting; the freine 10 from transmission gear-case by removing the bolts which secure the flanges .i9 enti 20 together and the `bolts securing the lugs i6 and 17 on the freine l0. The nio'torlcasing' is not utilized es e peri: of the snioporting structure so that it 'will not he snhiectecl to the stresses to which the soigner-ting sti-ne ture is snojeotetlu lfnrthermore, this meines it possible 'to use o, motor of ntendnrel riesige which is not neun-ily provided with e, eosinwl adopted to function es o portion of the geen eral supporting structure. Another :Ulventago of this construction is that the craniov cese oi the motor which is usually se'iarnte 'from the cylindorscnsing, muy he lowelefl through the frame While the cylinder-casing remains secured on the freine. rllhis is desirable in'inuking some repgiirs "to the motor.

A lug is formed on the underside of the rear portion of the mso 7 enel this lng hns e ionifitnflinel hole 2i therein, i refered Q5 extends through nml is Sliiiahle openingr 24 and its rea-ir enti is loivotetl5 es et 2G, to e laterally swinging durft-imi' 27 the rear emi` of which is adopted to he Connected to u plow or other implement to he operntea'l hy the tractor. A ensiiioivsprinfr 28 is interposed between the front emi of the ing 24 and :t nut Q5) adjacent the iront oi? the rofl Q5. A eherncteristii; of this con struction is that the tirait is eppliefi by the clronhnr direotly 'to e lug on the freer-ense i.

l ti

l' elaim as new which forms a part of the general support-- ing' structure.

Channel-laire are secured to lugs 3l on 'the axle-sleeves t5 and are connected at the rear by :triangle-bar 32 which is provided with holes 33 adapted to receive side-stops for the draw-bar LT. These bars are adapted to Support a platform on which the seat 353 is mounted.

The invention is not to be nndertood aS restrieted to the details set iortli, Since these may be modilied within the arope of the appended claims. without departingF from the spirit and eeope of the invention.

.l-'laif'ine thus described the invention, what l and desire to secure by Lettere latent, je:

l, ln atraetor, the combination oi 'front and rear axles, a supporting Sti-notare eemprising a transmission gear-ease extending around and inelosing one of said axles and an openirame haringl one ei its ends sui ported one the other axle and sides secured to the rear ease, and a motor seen red on said sides and removable,therefrom while the frame-Sides remain attarhed to the gear ease.

2. ln a tractor, the combination of from: and rear axles, a supporting structure eemprising a transmiesion gear-ease extending around and inelosing one oi'said axles and an open traine having,T one oi is ends. supported on the other axle and sides, and a motor having a easing' with one oit' its endein abutting relation to one end oi 'the `gear ease, the fratrie-sides being` attached to the gear ease beyond the joint between the motor-easing and gear-ease, the motor beingl secured to the frame-sides and removable Without weeen;

detaehingf the frame-sides from the gearease.

3. ln a tractor. the combination or front and rear axles, a supporting structure comprismel a, tranemissioir-gear ease extendingl around and inelosingg one of said axles, and an open frame lia-ving Sides, a pivotal oonnertion between one end of the trame and the other axle, and a motor having a easing .in almttimr relation to one end oi the gearrase, the trame havingA its Sides attached 'to the gear-case beyoi'ld the joint betweenthe motor easing; andthe rear-ease, the motor 'being mounted on the frame-Sides and removable without detaehing the frame from the emr-ease.

l.. ln a tractor. the Combination of front and rear axles, a supporting structure eemprising: a transmission gear-ease extending' around and inclosingi' one ol said axles. and a itl- Shaped Aframe having its Sides directly attached tothe grear 'ase and its connectingmember supported on the other axle. and a motor haring a asingiV seeured on the `,""ramesides and removable therefrom while the trame remains attached to the rear-rase.

5. ln a tractor, the combination of front and rear axles, a supporting structure comprising;- a transmission geanease extending' around and inclosing one of i aid axles, and. a lJ-shaped trame having its sides directly1 attached to the geanease, a. pivotal Connection between the connecting;` member of the frame and the'othe axle, and a motor l1avinel a easing secured onthe frame-sides and removable therefrom while the frame remains attached to the gear-ease.
